1 last stupid question, in my picture above do I need another power inserter for the solo hub for the Hopper3 and say 2 Joey clients? Since the one connected now is for the wally in the garage.
Only the one power inserter is needed. The power inserter is for the switch, not the hub. So, the way you have it connected now is actually the way I would prefer to do it, if I were installing it myself.
